The California Water Data Challenge, announced on Friday, invites interested individuals and teams to develop apps, websites, data visualizations or other tools “that leverage publicly available data sets in novel ways to support creative solutions to California’s water challenges, as outlined in the Brown administration’s California Water Action Plan,” according to a joint release by several state agencies supporting the competition. Sponsors of the challenge include the State Water Board, the California Department of Water Resources, California Fish and Wildlife, California Government Operations Agency, and the California Department of Technology.
